Instead of just cracking a joke, I should offer something more helpful, as well.
Much like @livebearerlove
, I find myself being prepared. Both for human & dog stuff but also for tank stuff.
USB-powered fans, pumps and air-sponge filters are really great. If you have large enough tanks, you can hide sponges behind hardscape or plants and run them in addition to whatever else you run. Or, if you only run sponge filters, it's no big deal. With planning, you can use decent cell phone back up batteries for quite a while.
Battery-powered air pumps also work well.
If you live in an area where you can't operate a generator, there are battery options that are affordable. I have ~$50 uninterruptible power supplies that have regular outlets and USB ports. They'll operate fans/pumps/filters for several days if you keep things on a timer. There are frequent outages here and they've worked well. Anyone telling you that they won't hasn't bothered to try newer batteries. With a little creativity and planning, they're convenient. Companies like Goal Zero also make larger battery solutions that will last much longer... and cost you a ton. Solar options, too.
Have some extra room in your home? Store water for frequent water changes. I live in a real life tiny house and still have room for an extra 50 gallons of RO/DI water. Plenty of different storage options on the market that are easy to disguise to fit your decor.
Think you'll have to evacuate or at least leave your area for an extended period of time? Make sure you have coolers with wheels so you can take your aquatic critters with you if that's an option. Fortunately with the internet, you can usually find someone with short notice to help you temporarily/permanently re-home things - should disaster strike - no matter where you end up. Folks can debate the ins and outs of that if they want but at least it's an option to have.
If you'll be leaving tanks at home and think there'll be flooding? Try to keep tanks up off the ground. That's a no-brainer, obviously, and it doesn't work in all situations. Because floating, movement, yada yada. But if you expect a few inches of water and are just keeping your smaller tanks on kitchen counters? Probably not a ton to worry about as far as tanks go. Also keep all of your supplies up high.
In the winter, I keep styrofoam insulation sheets (for shipping - so I already have it) to tape around my tanks to keep them at reasonable temperatures. Can help in the summer if things get too hot. That, small fans, floating frozen bottles/containers of water - or even bags of ice. Also keep rolls of decent plastic wrap (ugh, I know, I'm an environmentalist, too) for quickly covering tanks or containers.
Just do what you can reasonably do. Don't over-think things or get discouraged. Turn to the forum and social media for help if you need.
